yeah i mean if you can tell me how to use .litematic on baritone

this would be a question for baritone.
the .litematic format is supported for a year now. if your baritone version does not support it update baritone. make sure the schematic is in the "schematics" folder (if you use litematica that is the default location for schematics). you either can use the #build command or the #litematica command. should you need help with this commands you can use the #help build or #help litematica command or ask in the baritone discord.
note: baritone is not a schematic printer and it will run into problems with more complex schematics.
